Uniformly-heating material drying equipment for injection molding machine

Abstract

The invention discloses uniformly-heating material drying equipment for an injection molding machine. The uniformly-heating material drying equipment comprises a material drying box welded to the outer wall of the top of an injection molding machine body, one side of the material drying box communicates with the feeding end of the injection molding machine body through a discharging pipe, a mounting plate is welded to the lower portion of the outer wall of the other side of the material drying box, an air heater is installed on the outer wall of the top of the installation plate through bolts, the air outlet end of the air heater communicates with the interior of the material drying box through an air equalizing pipe, a first material guiding plate is welded to the upper portion of the inner wall of one side of the material drying box, and a second material guiding plate is welded to the lower portion of the inner wall of the other side of the material drying box. According to the equipment, the drying time of materials in the material drying box can be prolonged, so that the materials can be uniformly heated, the drying quality of the material drying equipment is improved, a pull rod drives a movable plate to reciprocate to change the discharging amount, the problem of low drying efficiency caused by excessive materials can be solved, and wet air in a feeding hopper can be preliminarily dried through a grid box.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to uniformly heated drying equipment for injection molding machines. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Divided into vertical, horizontal, all-electric. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity. The raw materials of plastic products are generally in the form of granules. Due to the fact that they are prone to moisture during transportation and storage, especially in the humid climate in the south, there is more moisture in the raw materials, which will easily lead to poor product quality and low yield when melted and injected. ...

Problems solved by technology

[0003] However, the existing drying equipment has some disadvantages during use: on the one hand, it is prone to uneven heating during heating, which leads to poor drying effect; on the other hand, it is impossible to pre-heat wet materials during heating. heating, resulting in low heating efficiency, and the inability to utilize the water vapor generated during the heating process, which will cause the water vapor to easily attach to the dried material again when it condenses into water, resulting in a decrease in the drying quality of the material
